Hi John, please fix your quoting of the previous mails, thanks! What ACPI defines does not matter at all. Linux uses 32-bit domains IDs, and on x86 specifily uses those for non-ACPI enumarated domains (e.g. VMD). You've also not demontrated any issue with any Linux driver yet. > Also...it would be nice if we could use Haiyang's patch as at least a > temporary fix, because distros are just today releasing the previous code, > and HyperV will start breaking "occasionally", depending on whether the > 32-bit virtual (fake) PCI domain fits within 16 bits. (If not, then we can > rush out a driver update to fix it, but there will be a window of time with > some breakage there.) Just send the fix to whatever driver is broken to the driver maintainer. But I can't find a single broken driver in the tree, and as you know nothing else matters for Linux anyway.
